/* Tube-sheets cluster — editorial journey UX (page-scoped helpers)
   Keeps NPRO navy/cyan/rust. Avoids stacked card grids.

   Geometry model (desktop):
   - Shells that paint a band (rail, navy chapter, meta-strip) stay full-bleed.
   - INNER content uses the same 1240 + 24px inset as .nav-inner / section.block.
   - Do not center each chip; keep a left-reading row on the content grid.
